River basin is considered to be perfect unit for management of the natural resources. Utilizing Remote Sensing and Geographical Information System (GIS) technique with mathematical models to assess the hydrologic parameters for the basin is being practiced widely now a day. In this work SWAT (Soil and Water Assessment Tool) having an interface with Arc MAP GIS software was used for the estimation of runoff yield of Uri river basin tributary of Narmada basin. The developed model was calibrated from the year 1999 to 2006 and validated for the period of 2008 to 2014. The coefficient of determination (R2) and Nash-Sutcliffe simulation efficiency (ENS) for the monthly runoff was obtained as 0.71 and 0.70 respectively for the calibration period and 0.70 and 0.69 respectively for the validation period.
